枪战：基准游戏。 [英] Shootout: the benchmarks game.
问题描述
下一个：
fannkuch基准
（c ++）
http://shootout.alioth.debian.org/gp...&lang= gpp& id = 2
（java）
g ++ -pipe -O3 -fomit-frame-pointer -finline-functions fannkuch.cpp -o
fannkuch.exe -march = native
jc -inline + fannkuch.class
时间秒当N增加
N 9 10 11
g ++ 0.047s 0.392s 5.013s
JVM 0.180s 0.689s 7.057s（-server -Xms64m） ）
JET 0.278s 0.820s 7.792s
C ++版本更快;然而，（给定JIT编译需要时间），
差异随着n = 11而减小。当n = 12（不包括在
枪战网站中）时，差异是均匀的较小的
1m34.648s（-server -Xms64m）
1m7.465s（g ++）
任何在这种情况下，JVM再次（略微）快于JET本机编译器
。

尝试使用N = 9,10,11请这些！

Next:
fannkuch benchmark
(c++)
http://shootout.alioth.debian.org/gp...&lang=gpp&id=2
(java)
g++ -pipe -O3 -fomit-frame-pointer -finline-functions fannkuch.cpp -o
fannkuch.exe -march=native
jc -inline+ fannkuch.class
Time in secs as N increases
N 9 10 11
g++ 0.047s 0.392s 5.013s
JVM 0.180s 0.689s 7.057s (-server -Xms64m)
JET 0.278s 0.820s 7.792s
C++ version is faster; however, (given JIT compilation takes time),
the difference decreases with n = 11. With n = 12 (not included in
shootout site), the difference is even smaller
1m34.648s (-server -Xms64m)
1m7.465s (g++)
In any case, JVM is again (slightly) faster than JET native compiler
in this case.
